      Heredity

    • C.

      Homeostasis

    • D.

      Cellulose

    Correct Answer
    B. Heredity
    Explanation
    Heredity refers to the passing of traits from parents to offspring. It involves the transmission of genetic information from one generation to the next. This process is responsible for the similarities and differences observed among individuals within a species. Through heredity, traits such as eye color, height, and blood type are inherited from parents and expressed in their offspring. Biology is the study of living organisms, homeostasis is the ability to maintain a stable internal environment, and cellulose is a complex carbohydrate found in the cell walls of plants.

  • 2. 

    The control group is manipulated in the experiment

    • A.

      True

    • B.

      False

    • C.

      Unknown

    Correct Answer
    B. False
    Explanation
    In an experiment, the control group is not manipulated. Its purpose is to serve as a baseline or comparison group against which the experimental group is measured. The control group is kept unchanged and is not exposed to the independent variable being tested. This allows researchers to determine the effect of the independent variable by comparing it to the control group, which represents the normal or non-manipulated condition. Therefore, the statement that the control group is manipulated in the experiment is false.

    Rate this question:

  • 3. 

    The ___ variable is the variable that is measured in an experiment

    • A.

      Homeostasis

    • B.

      Dependent

    • C.

      Independent

    • D.

      Control

    Correct Answer
    B. Dependent
    Explanation
    In an experiment, the dependent variable is the variable that is measured or observed. It is the outcome or result that is influenced by the independent variable. The independent variable, on the other hand, is the variable that is manipulated or changed by the researcher. The control variable is a variable that is kept constant or unchanged throughout the experiment to ensure that any changes observed in the dependent variable are due to the independent variable and not other factors. Homeostasis is not directly related to being a variable in an experiment, so it is not the correct answer.
